Frequently Asked Questions
Q: What equipment does the CR 82021-025 load wheel fit?
A: The CR 82021-025 is a tandem load wheel assembly engineered for Crown SP 36, SP 42, SP 48, and SP 3000 series electric lift trucks. It is an OEM-equivalent replacement for Crown part numbers CR 82021, CR 82021-A, CR 82021-010-A, and CR 82021-020-A.
Q: What are the wheel dimensions and material specifications for the CR 82021-025?
A: The CR 82021-025 features a 5 inch outside diameter, 4.12 inch tread width, and 2.44 inch bore. The wheel assembly has a non-marking Durarun 95A Shore A polyurethane tread bonded to a precision-machined carbon steel core. The assembly includes a needle bearing, sleeve, and thrust bearing for high-load performance.
Q: What is 95A polyurethane durometer and how does it perform in warehouse applications?
A: The 95A durometer rating indicates medium-firm polyurethane hardness. This durometer provides excellent load-carrying capacity while maintaining wear resistance in industrial warehouse environments. The non-marking formulation prevents floor staining common in high-traffic distribution centers.
Q: Which part numbers does the CR 82021-025 supersede or interchange with?
A: The CR 82021-025 supersedes CR 82021-A, CR 82021-010-A, and CR 82021-020-A. It is equivalent to CR 82021 and part number 82021. Verify your existing equipment documentation to confirm the correct replacement part for your specific Crown model.
Q: How does the steel core with polyurethane tread construction affect wheel lifespan?
A: The precision-machined carbon steel core provides superior dimensional stability and load distribution, extending wheel life under repetitive high-load cycles. The bonded polyurethane tread resists wear from friction while the integrated needle, sleeve, and thrust bearings reduce bearing failure, a common failure point in load wheel assemblies.
